Introduction
Devoted Son Jeong Jaesu Memorial Hall was constructed to honor the bravery of Jeong Jae-su who died at the age of 10 trying to rescue his father. It opened on June 12, 2001 at the former Sasan Elementary School where Jeong was a student.

In the Jeong Jae-su Exhibition Room on the first floor, materials relating to Jeong’s devotions are on display. In the Memorial Room on the second floor, various materials and works created by students are on display, as well as the classroom Jeong studied in. The theater shows movies about devotion as well as Jeong’s virtuous deeds. The theater is also used for seminars and conferences. There is also an outdoor performance stage, a facility for traditional folk games, and a rest area.
